Guía para saber qué cambió en la séptima edición del manual de publicaciones de la APA

1. Guide to What’s New in the
Publication Manual of the American
Psychological Association, Seventh Edition
This document provides an overview of what’s new in the seventh edition of the Publication Manual of the American
Psychological Association. Content throughout the manual has been significantly expanded and revised from the
sixth edition.
Chapter 1
Chapter 1 has new and updated content on scholarly
writing and publishing principles. This includes infor-
mation about
• types of journal articles and student papers,
• ethical and accurate reporting of research results,
• data retention and sharing (with additional data-
sharing considerations for qualitative research),
• contributions meriting publication credit,
• authors’ intellectual property rights during
manuscript review, and
• much more.
Chapter 2
Chapter 2 covers paper elements and formatting for
both professional and student papers. The summa-
ries of Publication Manual sections outlined here focus
mostly on changes that affect student paper format-
ting, though significant changes to professional papers
are also noted.
A sample professional paper and a sample student
paper are available on the APA Style website and in
the manual.
2.3 Title Page
NEW
The seventh edition includes guidelines for student paper
title page formatting that are different from professional
paper title page formatting. Student title page elements
include the course number and name, instructor name,
and assignment due date as well as the omission of the
running head. Students should follow the guidelines of
their instructor or institution when determining which title
page format is most appropriate to use. Sample student
and professional title pages are provided in the manual
(Figures 2.2 and 2.3) and in the title page guidelines on
the APA Style website.
2.4 Title
EXPANDED
The title of the paper should be in title case, bold,
centered, and positioned in the upper half of the title
page. See this section for additional guidelines.
2.5 Author Name (Byline)
EXPANDED
This section includes clearer instructions on how to
format a byline.

2. 2.6 Author Affiliation
REVISED
Affiliations for authors working at different institutions
now use a superscript format that involves using Arabic
numerals to connect author names to the appropriate
affiliations. For all authors, academic affiliations should
include the name of any department or division and the
name of the institution, separated by a comma. It is not
necessary to include the location of the institution unless
the location is part of the institution’s name.
Details and additional examples of affiliations are avail-
able on the APA Style website.
2.7 Author Note
REVISED
An author note is not required for student papers,
unless requested by an instructor. This revised section
includes information for authors of professional papers
about how to format the author note and new content
to be included (i.e., ORCID iDs, study registration,
open sharing practices).
2.8 Running Head
REVISED
• A running head is not required on student papers,
unless requested by an instructor.
• Professional manuscripts still include a running
head of 50 characters or fewer. The words “Running
head:” no longer appear as a label on the first page.
• See the professional sample paper on the APA
Style website for examples of the seventh edition
running head.
2.9 Abstract
REVISED
An abstract is not required for student papers, unless
requested by an instructor. This revised section
includes guidelines for formatting abstracts, including
structured abstracts.
2.10 Keywords
NEW
Keywords are not required for student papers, unless
requested by an instructor. This section includes guidance
about how to format keywords in professional papers.
2.11 Text (Body)
EXPANDED
This section describes how to format the text of the
paper, including considerations for paper organization.
The paper title appears at the top of the first page of
the text in bold and centered.
2.12 Reference List
REVISED
This section describes how to format the reference list.
The label “References” is now bold.
2.13 Footnotes
EXPANDED
This section has instructions on how to create a call-
out to a footnote in the text, number footnotes, and
format footnotes listed on a separate page.
2.14 Appendices
EXPANDED AND REVISED
This section has clearer guidance on how to label and
format different types of appendices. The label
“Appendix” is now bold.
2.15 Supplemental Materials
EXPANDED AND NEW
This section includes examples of and considerations
for content in supplemental materials as well as new
suggestions for making content accessible for all users.
2.17 Order of Pages
EXPANDED
This section outlines the order of pages in a paper,
including a more flexible placement of tables and
figures: either embedded in the text after they are first
called out or on separate pages after the reference list.
See also information on the order of pages on the APA
Style website.
2.18 Page Header
EXPANDED AND REVISED
This section includes instructions on where to place
elements in the page header and details revised
elements tailored to meet the different needs of
papers for professionals (page number and running
head) and students (page number only). See also infor-
mation on page headers on the APA Style website.
2.19 Font
REVISED
• Font guidelines are more flexible. This revised
section notes that “APA Style papers should
be written in a font that is accessible to all
users.” Section 2.19 provides the following font
recommendations:
° a sans serif font such as 11-point Calibri, 11-point
Arial, or 10-point Lucida Sans Unicode or
° a serif font such as 12-point Times New Roman,
11-point Georgia, or normal (10-point) Computer
Modern (the latter is the default font for LaTeX).
2

3. • Students and other authors may choose other fonts,
as needed, but should keep accessibility in mind
when doing so. The APA Style website contains
further discussion of font and accessible typography.
• Because different fonts take up different amounts
of space on the page, we recommend using word
count rather than page count to gauge paper
length (see Section 2.25 for more information about
paper length).
2.21 Line Spacing
EXPANDED
General guidance to double-space the paper is
provided, followed by line spacing for specific paper
sections: title page, table body, figure image, foot-
notes, and displayed equations. Do not add lines
before or after headings or between paragraphs.
2.22 Margins
EXPANDED
The section on margins addresses possible adjust-
ments needed for margins in dissertations and theses
compared to journal articles. See also information on
margins on the APA Style website.
2.23 Paragraph Alignment
EXPANDED
• This section describes how to align paragraphs to
the left margin. See also information on paragraph
alignment on the APA Style website.
• Formatting of long DOIs or URLs is outlined: (a) line
breaks should not be manually inserted, and (b)
breaks applied automatically by a word-processing
program are permissible.
2.24 Paragraph Indentation
EXPANDED
This section describes guidance for paragraph inden-
tation as well as exceptions needing different inden-
tation: title page, abstract, section labels, appendix
labels and titles, headings, block quotations, tables
and figures, and reference entries. See also infor-
mation on paragraph indentation on the APA Style
website.
2.25 Paper Length
EXPANDED AND NEW
This section includes a recommendation to use word
count rather than page count to determine paper
length when possible. When using word count,
count all words in text, references, table bodies,
table and figure notes, and appendices.
2.26 Principles of Organization
EXPANDED
This section includes a discussion of how and why to use
headings to effectively organize and structure a paper.
2.27 Headings
REVISED
The following table demonstrates how to format head-
ings in seventh edition APA Style. All headings are
bold; Levels 3 and 5 are also italic.
Level Seventh Edition Format
1
Centered, Bold, Title Case Heading
Text begins indented as a new paragraph.
2
Flush Left, Bold, Title Case Heading
Text begins indented as a new paragraph.
3
Flush Left, Bold Italic, Title Case Heading
Text begins indented as a new paragraph.
4
Indented, Bold, Title Case Heading, Ending
With a Period. Text begins on the same line and
continues as a regular paragraph.
5
Indented, Bold Italic, Title Case Heading,
Ending With a Period. Text begins on the same
line and continues as a regular paragraph.
For more details about how to format headings,
including headings in the introduction of a paper, see
information about headings and headings in sample
papers on the APA Style website.
2.28 Section Labels
REVISED
• All section labels (e.g., “Author Note,” “Abstract,”
“References”) are now bold.
• The chapter ends with full samples of both student
and professional papers with labels to show how
specific elements appear when implemented and
where in the manual to find more information.
Chapter 3
Chapter 3 orients writers to journal article reporting
standards (JARS) and includes tables outlining stan-
dards for reporting quantitative, qualitative, and mixed
methods research.
• JARS was significantly updated to provide
guidance for not only quantitative research but also
qualitative and mixed methods research.
3

4. • Substantial content in Chapter 3 and throughout
the Publication Manual addresses the unique needs
of qualitative and mixed methods researchers.
Chapter 4
Chapter 4 provides guidance on writing style and
grammar. Guidance has been updated and expanded
and new examples added throughout.
• The singular “they” is endorsed, consistent with
inclusive usage. Details and examples are in Section
4.18 as well as in the blog post on singular “they.”
• Improved guidance and specific examples help
authors determine what does and does not
constitute anthropomorphism (see Section 4.11).
• Expanded and new sections outline strategies
anyone can use to improve their writing.
Chapter 5
Chapter 5 presents bias-free language guidelines.
General guidelines for writing about all people with
inclusivity and respect have been updated.
• Guidance has been updated to reflect
best practices for discussing the following
characteristics:
° age (Section 5.3)
° disability (Section 5.4)
° gender (Section 5.5)
° racial and ethnic identity (Section 5.7)
° sexual orientation (Section 5.8)
• New guidance is provided for discussing:
° participation in research (Section 5.6)
° socioeconomic status (Section 5.9)
° intersectionality (Section 5.10)
Chapter 6
Chapter 6 covers the mechanics of style, including
punctuation, capitalization, abbreviations, numbers,
and statistics in text. Examples have been updated
throughout the chapter. Key changes are as follows:
• Use one space after a period (or other punctuation)
at the end of a sentence.
• Use double quotation marks to refer to a letter,
word, phrase, or sentence as a linguistic example or
as itself. See Section 6.7 and as well as the guidance
on quotation marks on the APA Style website.
EXAMPLES:
° the letter “m”
° the singular “they”
° answered “yes” or “no”
° Instead of referring to someone as a “defective
child,” talk about a “child with a congenital
disability” or a “child with a birth impairment.”
° Students wrote “I promise to uphold the honor
code” at the top of the test page.
• Use double quotation marks to present stimuli in the
text (long lists of stimuli may be better presented in
a table, where quotation marks are not needed).
EXAMPLE:
° The stimulus words were “garden,” “laundry,”
“briefcase,” and “salary.”
• Spelling in APA Style papers should conform to
the Merriam-Webster.com Dictionary. Spellings
of psychological terms should conform to the APA
Dictionary of Psychology. If a word appears differently
in these two dictionaries, follow the spelling in the
APA Dictionary of Psychology. If a word is not in
either of these dictionaries, consult an unabridged
edition of Webster’s dictionary. If the dictionary offers
a choice of spellings, select one spelling and use it
consistently throughout your paper.
• Section 6.11 specifies preferred spellings for
common technology words, including “internet”
(lowercase “i”), “email” (no hyphen), “ebook” (no
hyphen), and others.
• Expanded guidance is provided on the
capitalization of proper nouns, job titles, diseases
and disorders, and more (see Sections 6.13–6.21).
• Guidelines for the presentation of abbreviations
have been revised and expanded to address
common questions, such as how to include a
citation with an abbreviation and how to use
scientific and Latin abbreviations.
• New guidance is given on how to write gene and
protein names and abbreviations (see Section 6.31).
• Guidelines for the presentation of numbers have
been updated to be consistent throughout a work
(e.g., there is no longer an exception for presenting
numbers in an abstract).
• Updated guidelines allow greater flexibility for
lettered, numbered, and bulleted lists (see Sections
6.49–6.52). Bulleted lists do not need to be
punctuated as though they are complete sentences.
4

5. Chapter 7
• Chapter 7 includes expanded and revised guidance
on creating tables and figures and new samples
showing a range of basic and complex table and
figure types.
• Authors may place tables and figures in the paper
either after the reference list on separate pages
or embedded in the text near where they are first
called out.
• The accessible use of color in figures is addressed
(see Section 7.26).
• A table checklist is included in Section 7.20. A
figure checklist is included in Section 7.35.
• Tables and figures are now parallel: the formatting
of numbers, titles, and notes is consistent across
both (as outlined below).
Tables
• Bold the word “Table” and the number: Table 1
• The table title is in title case and italics.
• A diagram that illustrates the basic table
components is available online and in Section 7.9.
Figures
• Bold the word “Figure” and the number: Figure 1
• Figures now have titles, just like tables.
• The figure title is in title case and italics.
• Figures now have notes (instead of a caption) that
follow the same guidelines as table notes. Figures
can have general, specific, and probability notes.
• A diagram that illustrates the basic figure
components is available online and in Section 7.23
The APA Style website also contains many sample
tables and sample figures in seventh edition APA Style.
Chapter 8
Chapter 8 addresses appropriate levels of citation as
well as plagiarism, self-plagiarism, and other unethical
writing practices.
• New guidance is provided on how to cite recorded
or unrecorded Traditional Knowledge and Oral
Traditions of Indigenous Peoples (see Section 8.9).
• New guidance is provided on how to format quotations
from research participants (see Section 8.36).
• Information about plagiarism and self-plagiarism
has been updated (see Sections 8.2 and 8.3).
• An example of how to format epigraphs is now
included (see Section 8.35).
• In-text citations have been simplified and made
easier: For works with three or more authors,
include the name of only the first author and the
abbreviation “et al.” in every in-text citation, even
the first time a citation appears.
° Sixth edition style: First citation: Smith, Ellenio,
and Pruitt (2019) or (Smith, Ellenio, & Pruitt,
2019); subsequent citation: Smith et al. (2019) or
(Smith et al., 2019)
° Seventh edition style: Both first and subsequent
citations: Smith et al. (2019) or (Smith et al., 2019)
° See details and examples of narrative and paren-
thetical in-text citations on the APA Style website.
° When multiple references would shorten to the
same “et al.” abbreviation, disambiguate them
by spelling out as many author names as needed
to differentiate the citations and match them
to their reference list entry. These and other
guidelines (outlined in Sections 8.10–8.22) about
in-text citations are unchanged from the sixth
edition. Some details for in-text citations can be
found online as well.
Chapters 9–10
Chapters 9 and 10 work together; Chapter 9 contains
guidance, and Chapter 10 has the reference examples.
Chapter 9 includes
• expanded guidelines for creating references,
with specific sections focusing on each reference
element (author, date, title, and source) as well as
the format and order of a reference list
• new guidelines for formatting annotated
bibliographies
• updated guidance on when to include DOIs and
URLs for works retrieved from most academic
research databases as well as from proprietary
databases such as ERIC or UpToDate
Chapter 10 provides
• more than 100 new examples of APA Style
references grouped by category (periodicals,
books, book chapters, reports, dissertations, social
media, websites, etc.)
• templates in each category, so readers can
understand the building blocks needed to create a
reference for any type of work
• corresponding parenthetical and narrative in-text
citations for each reference
5

6. New Guidelines for All Reference Types
The number of authors included in a reference entry
has changed:
• Provide surnames and initials for up to and
including 20 authors. When there are two to 20
authors, use an ampersand before the final author’s
name: Author, A. A., Author, B. B., & Author, C. C.
• When there are 21 or more authors, include the
first 19 authors’ names, insert an ellipsis (but no
ampersand), and then add the final author’s name.
EXAMPLE WITH 21+ AUTHORS
Kalnay, E., Kanamitsu, M., Kistler, R., Collins, W.,
Deaven, D., Gandin, L., Iredell, M., Saha, S., White,
G., Woollen, J., Zhu, Y., Chelliah, M., Ebisuzaki, W.,
Higgins, W., Janowiak, J., Mo, K. C., Ropelewski,
C., Wang, J., Leetmaa, A., . . . Joseph, D. (1996).
The NCEP/NCAR 40-year reanalysis project. Bulle-
tin of the American Meteorological Society, 77(3),
437–471. https://doi.org/10.1175/1520-0477(1996)0
77%3C0437:TNYRP%3E2.0.CO;2
For more on why this change was made, see the blog
post on the number of authors to include in a reference.
• The presentation of DOIs and URLs has been
standardized.
° Both are presented as hyperlinks.
° The label “DOI:” is no longer used before a DOI.
DOIs should begin with the prefix https://doi.org/
° The words “Retrieved from” are used before a
URL only when a retrieval date is also needed;
otherwise, URLs are presented without a label.
° The APA Style website also contains guidance
on DOIs and URLs.
• For any reference with a publisher or a site name:
° When the author name and the publisher are an
exact match, the publisher is omitted.
° The word “Author” is no longer included
in the source element of the reference as a
replacement as in the sixth edition.
EXAMPLE
American Psychiatric Association. (2013). Diag-
nostic and statistical manual of mental disor-
ders (5th ed.). https://doi.org/10.1176/appi.
books.9780890425596

tic and statistical manual of mental disorders (5th
ed.). American Psychiatric Association. https://
doi.org/10.1176/appi.books.9780890425596
The author name in this reference (American Psychi-
atric Association) is also the name of the publisher, so
the name appears only once in the reference (in the
author element). The source element of the reference
includes only the DOI.
• The seventh edition includes expanded guidelines
and examples for citing works that are written in
another language (see Sections 9.38 and 9.39 as
well as the examples in Chapter 10).
10.1 Journal Articles
• When an issue number is present, always include it
(in parentheses and not italicized) after the volume
number.
EXAMPLE
Grady, J. S., Her, M., Moreno, G., Perez, C., &
Yelinek, J. (2019). Emotions in storybooks: A
comparison of storybooks that represent ethnic
and racial groups in the United States. Psychol-
ogy of Popular Media Culture, 8(3), 207–217.
https://doi.org/10.1037/ppm0000185
• If a journal uses article numbers, include the word
“Article” and the number instead of any page range.

https://doi.org/10.1371/journal.pone.0209899
10.2 and 10.3 Books and Book Chapters
• Do not include physical locations for publishers
in any reference type. Whereas a sixth edition
reference included “Washington, DC: SAGE.,” a
seventh edition reference now says only “SAGE.”

Without a DOI:
Burgess, R. (2019). Rethinking global health: Frame-
works of power. Routledge.
• For ebooks, the format, platform, or device
(e.g., Kindle) is not included in the reference. For
audiobooks, include the narrator and audiobook
notation only in specific cases (see Examples 22
and 29).
• Religious works and ancient Greek or Roman works
are cited in the text (see Section 9.42 and Examples
35–36 in Chapter 10).
10.4 Reports and Gray literature
• Reports follow a standard format. Examples are
given for government and other reports written by
an agency, individuals, or a task force.
• This category also includes examples for annual
reports, press releases, codes of ethics, grants,
and more.
10.5–10.16 Other Reference Types
New examples are included for dissertations, TED
Talks, TV series, webinars, YouTube and other stream-
ing videos, albums, songs, podcast episodes, radio
interviews and speech audio recordings, albums and
songs, artwork in a museum, clip art or stock images,
infographics, photographs, PowerPoint slides or
lecture notes, Twitter, Facebook, Instagram, Reddit,
webpages on news websites, and many more.
The APA Style website contains additional reference
examples.
Chapter 11
Chapter 11 presents expanded guidance and updated
examples for more types of legal references. Guide-
lines from The Bluebook: A Uniform System of Citation
continue to be the foundation for APA Style legal refer-
ences, with some modifications.
Chapter 12
Chapter 12 provides guidance on the publication
process.
• New content helps early career researchers adapt
a dissertation or thesis into a journal article or
articles, select a journal for publication, avoid
predatory or deceptive publishers, and navigate
journal submission.
• Sections on understanding the editorial publication
process illuminate the role of editors, the peer
review process, and criteria for evaluating
manuscripts.
• Sections 12.9 to 12.13 describe how to prepare a
manuscript for submission, how to use an online
submission portal, how to write a cover letter, and
more.
• Sections 12.14 to 12.18 on copyright and
permissions include general guidelines for
reprinting or adapting materials and information
about copyright and fair use.
• New guidance helps authors share and promote
their work following publication.
